In the past we've already talked about a cyclist who uses his phone to call a friend. We also had a texter, who texts while on bike.
But to be fair to those guys, they were just conversing and texting far from traffic, while not posing a threat to bystanders.
However, in the case of the phone talker above, who I caught redhanded, he was cycling with one hand, talking with the other and the only reason he stopped was a red light and the crossing traffic on N11.
I guess some cyclists are too busy to waste time on stopping for using their phone.
I took the photo on 22 May 2012 at the (relatively) new cycle route by the Grand Canal.
